Diminishing Returns in Cardiovascular Disease Research: Systematic Review and Meta-analysis
DownloadFall 2019
If “usual care” improves with time, it becomes increasingly difficult for new therapies to demonstrate additional benefit. Our objective then was to determine, by systematic review of randomized trials, whether the absolute cardiovascular risk reduction attributed to community-implemented...
